摘要

A vane for turbomachinery, such as, for example, an aircraft turbojet or turbofan engine, or an aircraft turboprop engine. The vane includes: (i) a first deicing fluid flow circuit inside the vane; (ii) a second deicing fluid flow circuit inside the vane; and (iii) a selector for directing the majority of the fluid towards the first circuit when the turbomachinery is in a first operating state, and for directing the majority of the fluid towards the second circuit when the turbomachinery is in a second operating state.
